Embodiment 1
[0018] Embodiment 1: as Figure 1-5 As shown in Fig. 1, a method for drilling an efficient and fast drawing of the map, taking the drawing of the completion map of the pre-drained coal seam strip gas by drilling through the seam as an example, includes the following steps:
[0019] Step 1, such as figure 1 As shown, in the Excel software, the internal data of the drilling construction ledger is read through the internal retrieval function, and it is referenced to the specified location, including the drilling hole number, azimuth, inclination, hole depth, coal seeing, actual The number of pipes, actual pipe length, number of screen pipes, length of screen pipes and other parameters.
[0020] Step 2, such as figure 2 As shown, manually input the drawing frame parameters of the drilling profile in the Excel software, including the starting point of the profile frame, the size of the frame, the starting elevation of the section line, the elevation of the roadway, and the size ...

The invention discloses a method for efficiently and quickly mapping a drill hole. The method comprises the following steps: (1) reading a drill hole completion ledger by Excel software to extract various parameters of the drill hole; (2) defining a frame height, a length, a contour line, an initial elevation, a roadway parameter, a roadway relative position, a relative position of a drilling opening point and a roadway, and a planar graph output position; (3) converting the three-dimensional space parameters of the drill hole into two-dimensional space parameters through Excel software; (4) compiling a CAD external drawing command in Excel software, embedding the drilling two-dimensional space parameters into the drawing command, and generating a drilling drawing command set; and (5) copying the drawing command group to an AutoCAD software command input window to realize the drawing of the drilling drawing. According to the invention, batch drawing of drill holes is realized, so that the workload of drawing a drill hole completion graph is reduced, and the working efficiency and accuracy are improved.
Description
technical field [0001] The invention relates to a high-efficiency and fast mapping method for drilling, and belongs to the technical field of high-efficiency and rapid drilling. Background technique [0002] As the mining depth of underground coal mines increases, the gas pressure and gas content in coal seams will also gradually increase, and gas control becomes more and more difficult. Gas control in outburst coal seams is mainly carried out by mining protective layers or by drilling pre-pumping methods. Currently, the commonly used The methods of drilling gas extraction include: pre-draining coal seam gas in the coal working face by drilling in the current layer, pre-draining coal seam gas in the excavation working face by drilling in the current layer, pre-extracting coal seam strip gas in the excavation working face by drilling through the layer, and There are five types of gas in the pre-extraction of Shimen coal mining area by drilling and pre-extraction of gas in the...
